ABSTRACT:
A unitary cylindrical sleeve is provided for receipt in a trumpet or flumme for use in bottom pouring steel processing operations. The ceramic sleeve includes an inner tubular metallic or plastic shell which receives on the outside thereof a ceramic outer shell. The ceramic sleeve is deposited into and temporarily supported within the trumpet. The combination of trumpet and sleeve is then maneuvered over a receiving spider on a sprue plate of an ingot mold system. Operators need only engage the combination when lowered into close proximity with the sprue plate.
